Car Rentals in Patagonia

We have an upcoming trip where we will be flying to different regions within Patagonia and then renting a car for 4 -10 days in each place. I'd love to get recommendations for car rental companies in these locations:

In Chile, Econorent is usually the cheapest option with reliable cars. Expect to pay a small fortune for an automatic, and also expect that your automatic will not be there when you arrive, and if you don't drive a manual, you're screwed.

we picked up a car and returned it in el Calafate. We used hertz. We drove to Torres del Paine. The only problem was the border crossing from Chile into Argentina TOOK A VERY LONG TIME at the Argentinian border crossing and also returning from Chile to Argentina. Make sure to get your documents stamped at the border and have permission from hertz to go to Argentina and have proper insurance. Getting gas in Torres del Paine was another challenge. We also missed the turn going to the Argentina/Chile frontier from el Calafate. we also used the rental car to go to Perito Moreno. Be careful of the winds there; they can blow the doors off a car.
overall no problems other than the border crossing from and back to Chile.

El Calafate, Argentina

Punta Arenas, Chile

Puerto Montt, Chile

Thanks.

I rented a car at the El Calafate airport and drove to Torres and Punta Arenas. I booked it through budget (budget.com.ar) I was able to reserve months ahead of my arrival which saved me money due to Argentina's inflation. In Argentina, not so much in Chile, you have to be aware of two things: Gas stations and roads. Many are gravel roads in very poor conditions. The border crossing can be slow or fast. I had arrived during lunch, and I had to wait until somebody from customs showed up (I opened and closed the border chain myself while they were eating).
If you're rental an economy car don't risk it and take the good roads and ALWAYS check for the spare tire before leaving the rental site.

If you travel to Torres del Paine in Chilean Patagonia, beware of the gravel roads. I have seen many overturned rental cars, and it's a long wait for a tow. I generally hire local drivers with appropriate vehicles and experience.
